Step 1: Compute the pooled variance. Hint: use the standard deviation of each sample to get the variance of each sample and then use the variance of each sample to solve for the SS for each sample. Remember that the s2 = SS/df. Plug in what you know and solve for what you do not know. (2 points) Fill in this table to get started: n df M S s2 SS Country owners 20 a 15 4 City owners 22 10 3 Step 2: Compute the standard error of the mean difference (2 points)
Step 3: Compute t (the test statistic) (2 points) d. Make a decision and state your conclusion both in words and in statistical notation. (4 points) 5. To maximize the power of a statistical test (e.g., a t-test), we need to minimize error. What is one way in which we can minimize error? (1 point)
